Question

I (unfortunately) have some dates that were saved into varchar columns. These columns contain dates in the following format:

mmddyy

For example:

010110

I need to import these values into a table which is set to datetime and formats dates like this:

2010-09-17 00:00:00.000

How can I convert the string above into a datetime value below?

Answer 1

The CAST function will do this, the problem is that it will assume you first 2 digits are year. This should for for you:

SELECT CAST((RIGHT('010110',2) + LEFT('010110',4)) AS DATETIME)

This is assuming that all dates are MMDDYY.
